Opening a business bank account outside your home country almost always requires translated documents. In many cases, those translations need to be certified. The exact requirements depend on the destination country, the bank, and the type of legal entity involved. There is no universal standard, and getting this wrong at the documentation stage can delay the process by weeks.
What foreign banks typically require
Most banks outside the company's country of incorporation ask for a set of documents that confirm the company's legal existence, the identity of its representatives, and the legitimacy of the planned transactions. The most commonly requested documents include:
- Certificate of incorporation or commercial register extract
- Articles of association or shareholders' agreement
- Minutes of director or officer appointment
- Powers of attorney authorising account signatories
- Identification documents for beneficial owners
- Proof of registered address
- Recent financial statements, in some cases (balance sheets, profit and loss accounts)
All documents issued in the company's home country arrive at the bank in the original language. To be accepted, they need to be translated into the official language of the destination country. In several markets, translation must be accompanied by certification or an apostille.
When certified translation or apostille is required
This area causes considerable confusion. Three distinct concepts are worth understanding clearly.
Plain translation: Accepted by a bank only when it has staff fluent in the source language or specifically waives certification. This is uncommon outside markets with strong ties to the source language.
Certified translation: Produced by a qualified professional translator and accompanied by a declaration of accuracy. This is the most common requirement at banks in the European Union, the United Kingdom, and the United States for corporate documents.
Sworn or notarised translation: Required when the original document was issued by a public authority and needs to carry legal effect in another jurisdiction. Different countries handle this differently: some recognise translations by court-sworn translators; others require notarisation or consular legalisation.
Apostille (Hague Convention): This is not a translation. It is a certification of the original document that authenticates it for use in countries that are parties to the Hague Convention. Many banks request an apostille on the original document and, separately, a certified translation of the apostilled version.
Before ordering any translation, it is worth confirming the precise requirements directly with the destination bank. What a German bank requires for a Portuguese company account differs from what a bank in the UAE or Singapore will ask for.
Requirements by market: the key differences
Some relevant differences across the most common destination markets:
Germany / France / Spain: Certified translation into the local language is required. Public documents, such as commercial register extracts or notarised minutes, typically need an apostille. Translation by a court-recognised sworn translator is accepted as standard.
United Kingdom: British banks accept certified translation by a specialist company, with a declaration of accuracy and reference to the translator's qualifications. An apostille on EU documents is not always mandatory, though some banks request it regardless.
United States: American banks typically require certified translation with a sworn statement or certification of accuracy from the translator. Public documents may require an apostille or consular legalisation depending on the issuing country.
Angola / Mozambique: Both are Portuguese-speaking countries, so documents issued in Portugal are accepted in the original. The reverse applies when a locally registered company presents documents to a Portuguese bank.
UAE / Singapore / Hong Kong: These markets have stringent requirements. Translation into Arabic or English is standard, and notarisation or consular legalisation is frequently required, depending on the document type.
This variability is precisely why a specialist financial translation provider is valuable beyond the linguistic work: they can guide the process for each specific market and document type.
Common mistakes that delay account opening
The most frequent causes of delay in this process fall into four categories:
- Translation without certification: the bank rejects it and requests a new version with a declaration of accuracy, adding days to the timeline.
- Apostille on the original but not on the translation: some banks require the apostille to accompany the translated document, or ask for the translation to be made from the already-apostilled original.
- Inconsistent legal terminology: corporate terms translated too literally can create ambiguity. "Gerente" rendered as "manager" instead of "director" in a power of attorney may raise questions about the scope of authority.
- Outdated documents: commercial register extracts and certificates of good standing have validity periods. Many banks reject documents older than three months.
The terminology point matters most in documents with legal effect. A single mistranslated term can call into question the validity of a power of attorney or the identity of the authorised signatory.

Frequently Asked Questions
Is sworn translation always required to open a business bank account abroad?
Not always. Many banks accept certified translation with a declaration of accuracy from a qualified translator, without the need for a sworn or notarised translation. Requirements vary by country and institution, so it is advisable to confirm directly with the destination bank before ordering translations.
What is an apostille and when is it needed for banking documents?
An apostille is a certification that authenticates public documents for use in countries party to the Hague Convention. Many banks require an apostille on original documents issued by public authorities, such as commercial register extracts. An apostille does not replace translation: both may be required simultaneously.
Which corporate documents do foreign banks most commonly request?
The most common are a certificate of incorporation or commercial register extract, articles of association, minutes of director appointment, powers of attorney, and proof of registered address. Some banks also request recent financial statements depending on the account type and anticipated transaction volume.
Will a plain translation without certification be accepted by a bank?
Rarely. Most banks outside the company's home country require certified or sworn translation for corporate documents. A translation without a declaration of accuracy and clear identification of the translator is frequently rejected during document review.
How long does certified translation of corporate documents take?
Turnaround depends on the volume of documents, the language pair, and the certification level required. For a typical set of corporate documents, delivery in two to five business days is standard. Rush processing may be available for urgent cases.
